Shot Blast Services / Surface Preparation

We offer shot blast services to anyone needing to clean their concrete surface and have it prepared for any particular coating application or resealing. We have the equipment to remove any type of coating that needs to be removed.

Shot Blasting provides a clean dry profiled substrate that allows for paints, coatings, and overlays to mechanically bond. Our equipment is very efficient and can execute larger square foot areas. All the dust is collected while we run our shot blasters.

Shot blasting removes laitance from the surface which is a weak layer of cement at the top of the concrete. It also removes sealers and other thin coatings.Shot blasting is a preferred method for preparing concrete surface that have any of the following: dirt, oil, grease, curing compounds, sealers, paint, rubbers from tires, etc This step is imperative to get proper adhesion for almost any cement coating.
We do not always shot blast before striping but always let the customer know that it is important for adhesion.

SERVICE DETAILS

As shot blasting goes hand in hand with our work this part of our business has become something we do in addition to ware house line painting. Since surface preparation is almost always over looked when people have there lines painted we wanted to explain as much as we could about the process.
The ICRI (International Concrete Repair In has set standard guide lines for different shot blast profiles. Thicker concrete coatings have more aggressive concrete profiles. The paint we install is usually less than 15 mills so a light shot blast is sufficient for what we do.

This was a coating at the the public pool bathrooms in the City Of Rocky River, Ohio. The coating failed after it was installed with improper floor preparation. We were contacted to remove the gray coating (epoxy) and have it ready to be re coated. We had to shot blast this and grind it in a multiple step process.
Below you can see how shot blasting will remove the coating.

On this project we were asked to remove the markings. This warehouse was being reconfigured and they needed the markings completely eradicated. We shot blasted the lines off the concrete and the owner was okay with the finish. There are always options if the shot blasted finish is now what is desired at the end of the job. Some options to consider are resealing where the markings were. Re polishing the concrete so to bring back smooth sheen to the floor. Shot blasting will very lightly break through the concrete so the pores are open some.
REMEMBER!
We have other methods of removal but other methods require different time tables for completion and different equipment.

Shot Blasting
We offer shot blast services to anyone needing to clean their concrete surface and have it prepared for any particular coating application. We have the equipment to remove any type of coating that needs to be removed.

Shot Blasting provides a clean dry profiled substrate that allows for paints, coatings, and overlays to mechanically bond. Our equipment is very efficient and can execute larger square foot areas. This is the ideal method of preparation since is cleans and profiles the floor at the same time. Coatings can be applied directly after unlike water blasting and grinding with water attachments.
Advantages of Shot Blasting
No need to use toxic chemicals
High Production Without Dust. We can prepare up to 10,000 square feet per hour
Shot Blasting can be performed indoor or out door on parking garages and airport run ways
Coating can be applied right after shot blasting is completed

Industry guidelines for creating surface profiles

The International Concrete Repair Institute (ICRI)
has created a technical guideline #03732,
“Selecting and specifying concrete surface preparation for sealers, coatings, and polymer overlays.” This guideline provides concrete surface profiles of CSP 3 to 9 which are used under the following conditions.

• For coating applications from 4–5 mils in thickness, the surface profile shall be a CSP 3.
This is known as a light shotblast.

• For coating applications from 15–50 mils in thickness, the surface profile shall be a CSP 4
or 5. This is known as a medium shotblast.

• For coating applications from 40 mils to 1/8″ in thickness, the surface profile shall be a CSP 5
or 6. This is known as a medium-heavy shotblast.

• For topping applications from ¼” to ½”, the
surface profile shall be a CSP 6 or 7. This is
known as a heavy shotblast.

• For concrete overlays greater than ½”, the
surface profile shall be a CSP 8 or 9. This is
known as an extreme shotiiiiiblast.
